### E ˚ sign for reaction to occur

For the reaction to occur does E ˚ have to be positive?

### Re: E ˚ sign for reaction to occur

A reaction can still occur even if Eº is negative, but it is favorable to have a +Eº because this will make your ∆Gº negative through the equation ∆Gº= - nFEº, and the reaction will occur spontaneously.

If you have a -∆Eº, the reverse reaction will be favorable.

Hope this helps!
